Embodiment Construction

[0020] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0021] Such as Figure 1 to Figure 3 As shown, the incubator of the present invention, an embodiment thereof, includes a casing (not shown), an inner bag 11, a control system (not shown) and a heat balance stabilization mechanism, the inner bag 11 is arranged in the outer casing, and the inner bag 11 The outer surface is surrounded by heating wires and cooling tubes (not shown in the figure). The control system is used to calibrate the temperature of the sensor to be calibrated. The inner tank 11 surrounds the cavity 12. The thermal balance stabilization mechanism is arranged in the cavity 12 and is isolated from the inner tank 11. . In one embodiment, the thermal balance stabilization mechanism includes a housing 24 and a detection chamber, the housing 24 is made of a heat-conducting material, such as metal, silicone sheet or he...

Abstract

The invention discloses an incubator, comprising a housing as well as an inner container and a control system which are both arranged in the housing, wherein a cavity is surrounded by the inner container. The incubator also comprises a thermal equilibrium stability mechanism arranged in the cavity, wherein the thermal equilibrium stability mechanism comprises a shell and a detecting chamber, the shell is made of a heat conduction material, the detecting chamber at least comprises a first chamber and a second chamber which are mutually isolated, the first chamber is provided with a first through hole communicated with the cavity, and the second chamber is provided with a second through hole communicated with the cavity. According to the incubator, the thermal equilibrium stability mechanism made of the heat conduction material is arranged in the cavity surrounded by the inner container, the thermal equilibrium stability mechanism comprises the shell, the first chamber and the second chamber, and a reference sensor and a sensor to be calibrated are respectively placed in the first chamber and the second chamber, therefore, thermal equilibrium can be quickly established in the detecting chamber, and the temperature difference of the first chamber and the second chamber can be less than 0.001 DEG C. The incubator has a simple structure and low cost, and furthermore, high-precision temperature calibration can be realized.

Description

technical field [0001] The invention relates to a constant temperature box. Background technique [0002] In the manufacturing process of products such as sensors, due to the individual differences of products, it is usually required to be marked with consistency before leaving the factory. When marking, temperature stability is very important, so high-precision thermostat equipment is required. The existing common incubator has low precision, and the general internal temperature difference is ±0.5°C, while the high-precision incubator has complex structure and expensive price. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a constant temperature box with simple structure and low cost for the deficiencies of the prior art. [0004] The technical problem to be solved in the present invention is solved through the following technical solutions: [0005] A constant temperature box, comprising an outer shell, an ...
